Hair styling device

ABSTRACT

A flat strip of rigid material is transversely divided into a handle portion and a double-edged working portion. The handle portion is tapered to a free end for additional use as a hair divider. The double-edged working portion is longitudinally divided into combing and cutting edges transversely reduced from a thicker middle section. Comb teeth are defined in one of said double-edges and in the other a longitudinal recess terminates transversely in angular serrations that are spaced longitudinally apart the width of a serration. A blade holder, with a blade slidably mounted therein, is fixed in said recess with the blade guarded by the serrations. A longitudinally operable push-button is mounted near an inboard end of the blade holder in a slot longitudinally aligned therewith and, in extension thereof, positions the blade in the blade holder with respect to the angular serrations to sequentially expose blade portions originally behind the serrations.

[5 7 ABSTRACT A flat strip of rigid material is transversely dividedinto a handle portion and a double-edged working portion.

The handle portion is tapered to a free end for additional use as a hairdivider. The doubleedged working portion is longitudinally divided intocombing and cutting edges transversely reduced from a thicker middlesection. Comb teeth are defined in one of said doubleedges and in theothera longitudinal recess terminates trarisve rselyin angularserrations that are spaced longitudinally apart the width of aserration. A blade holder, with a blade slidably mounted therein, isfixed in said recess with the blade guarded by the serrations.

A longitudinally operable push-button is mounted near an inboard end ofthe blade holder in a slot longitudinally aligned therewith and, inextension thereof, positions the blade in the blade holder with respectto the angular serrations to sequentially expose blade portionsoriginally behind the serrations.

2 Claims, 4 Drawing Figures HAIR STYLING DEVICE The invention relatesgenerally to hair styling devices and more particularly to a manualrazor hair cutting device.

It is old in the art to style hair with a razor and a comb.

It is an object of the invention to provide a single manually operabledevice for styling hair.

Another object of the invention is to provide means for razor cuttinghair that doubles the life of a guarded cutting blade.

Other objects and a more complete understanding of the invention may behad by referring to the following description, claims and drawings, inwhich:

FIG. 1 is a perspective view of the invention from above and to one sideend,

FIG. 2 is an enlarged perspective exploded view of movable parts of theinvention,

FIG. 3 is an enlarged view of a blade usable with the invention, and

FIG. 4 is similar to FIG. 1, showing the invention less moving partsshown in FIGS. 2 and 3.

Referring to FIG. 1, the invention comprises an elongated flat strip ofrigid material that is divided transversely into a handle portion and adouble-edged working portion 11.

In the double-edged working portion 11, one of the double-edges defineda comb l2, and the other a longitudinal recess 13 (see FIG. 4) withangular serrations 14. The handle portion 10 tapers to a hair-dividingsharp end 16. At the juxtaposition of handle portion 10 and workingportion 11, a push button 18 is slidably mounted in a slot 19 definedtherein adjacent to a thumb recess 20.

Referring additionally to FIGS. 2 and 3, a blade 22 is adapted toslidably engage in a track 26 and a blade holder 24 which is fixed inrecess 13 by means of a threaded bolt 25 at the outboard end of saidblade holder. In the middle, retaining track 26 engages blade 22 in theblade holder for a portion of its length. Track 26 is prevented fromescaping from the blade holder 24 by a stop 34 at one end of said bladeholder and stop 38 adjacent the other end. The square profile of thetrack holds the blade firmly therein, the track itself being springilyengaged by blade holder 24.

Push button 18 defines a shoulder 28 in a longitudinal foot 30, and endof which engages an inboard end of track 26 in passing over an extendedlip 32 of blade holder 24 to hold that end of the blade holder in recess13. Shoulder 28 cooperates with overcut inboard end of the blade holderas a stop in the longitudinal travel of the push button in ejecting anold blade from the track and blade holder.

Referring to FIGS. 1 and 4, retaining guides 36 and 40 extendtransversely horizontal from foot 30 of the push button and engage inparallel grooves 37 and 41 defined in opposite walls of slot 19 toslidably support said push button 18 in slot 19. When a blade 22 isfully inserted into blade holder 24 and track 26, push button 18 ispushed to the inboard end of slot 19, and an arrow 44 inscribed on saidpush button falls opposite a base index mark 46. The outboard ends ofblade 22 and blade holder 24, which is recessed into end recess 42, thencoincide. Sliding push button outwardly to coincide with a second indexmark 48, that is longitudinally spaced from the index mark 44 by thewidth of a serration, advances the blade to a position flush with anoutboard end of working portion 11 in recess 42 and exposes portions ofthe blade 22 originally positioned behind serrations 14. Furtheradvancing push button 18 until shoulder 28 engages the inboard end ofblade holder 24, pushes the outboard end of blade 22 clear of recess 42and the outboard end of working portion 11 for grasping by the fingersto complete removal therefrom for the insertion of a new blade.

What is claimed is:

l. A hair styling device comprising: a pointed handle for holding thedevice and for dividing hair; doubleedged working means unitarily inalignment with said handlemeans for styling said hair; comb meansdefined in one edge of said double-edged working means for combing outsaid hair; recess means defined in a second edge of said double-edgedworking means; blade means having a cutting edge and slidably mountedwith said cutting edge exposed in said recess means; angular serrationmeans defined in said second edge for guarding the cutting edge of saidblade means, said serration means having serrations spaced apart thewidth of a seration; and push button means slidably mounted in saiddevice and adapted to longitudinally slide said blade in said recessmeans between two fully engaged positions therein spaced a serrationapart, thereby doubling the working life of said blade means bysequentially exposing the cutting edge of said blade means, includingthe parts originally shielded behind said serration means.

2. A hair styling device as described in claim 1 wherein said two fullyengaged positions of said blade means in said recess with respect tosaid serration means is indicated by coincident markings on said pushbutton means and said double-edged working means.

1. A hair styling device comprising: a pointed handle for holding thedevice and for dividing hair; double-edged working means unitarily inalignment with said handle means for styling said hair; comb meansdefined in one edge of said double-edged working means for combing outsaid hair; recess means defined in a second edge of said double-edgedworking means; blade means having a cutting edge and slidably mountedwith said cutting edge exposed in said recess means; angular serrationmeans defined in said second edge for guarding the cutting edge of saidblade means, said serration means having serrations spaced apart thewidth of a seration; and push button means slidably mounted in saiddevice and adapted to longitudinally slide said blade in said recessmeans between two fully engaged positions therein spaced a serrationapart, thereby doubling the working life of said blade means bysequentially exposing the cutting edge of said blade means, includingthe parts originally shielded behind said serration means.
 2. A hairstyling device as described in claim 1 wherein said two fully engagedpositions of said blade means in said recess with respect to saidserration means is indicated by coincident markings on said push buttonmeans and said double-edged working means.
